What an SEO agency does

Search engine optimization, or SEO, covers everything that helps a website show up in the unpaid results of search engines. Unlike an ad, a top position can’t be bought: you earn it by giving Google reasons to prefer you over your competitors.

  2. 2AI answersAI Overviews, ChatGPT and Perplexity draw on web pagesThe extension
  3. 3AdsA paid spot that disappears with the budgetNot SEO

An SEO agency handles this work from start to finish. It begins with a diagnosis, pinpoints what’s holding the site back, then builds an action plan and carries it out with you: technical fixes, new pages, rewrites of existing content, links earned from reputable sites. Every month, it measures what moved and adjusts the priorities.

The job changed when answer engines arrived. Google’s AI-generated overviews, ChatGPT and Perplexity also rely on web pages to build their answers: a site that’s well structured, cited by others and written to answer the real questions its customers ask stands a strong chance of appearing there. SEO remains the foundation; visibility in AI is its extension.

Finally, there’s what no agency can promise. Google puts it bluntly on its page about hiring an SEO: no one can guarantee a #1 ranking. A serious agency commits to a method, deliverables and honest reporting on results, not to a ranking.

Six workstreams, one strategy

Good SEO never relies on a single lever. We handle technical SEO, content and site authority together, because a perfect page Google never crawls is useless, and a fast site without useful content won’t rank.

  • SEO audit – The starting point

    The starting point

    A full review of your site and your competitors, so you know what to fix first.

  • Technical SEO

    A site Google understands

    Crawling, indexing, speed, mobile version, redirects, structured data: we remove the roadblocks that hide your pages from Google.

  • Content & keywords

    Answering the right questions

    Research into what your customers search for, page architecture, content briefs and optimization of the content already live.

  • Link building & authority

    Getting cited by others

    Links earned from real, relevant sites, digital PR, and link disavowal only in cases where Google calls for it, after a manual action.

  • Local SEO

    Win your city

    Google Business Profile, customer reviews, consistent business details and local pages to show up in the Map Pack.

  • AI visibility

    ChatGPT, Gemini, AI Overviews

    Tracking of your brand’s citations on a sample of typical questions, and content designed to be picked up by answer engines.

A roadmap with dates, not a vague promise

Every engagement follows the same sequence. The first month is about understanding the site and its market: the audit is delivered, then the strategy that comes out of it, with a clear order of priorities. Then come the months of execution, where we fix, publish and earn links, while a monthly report tracks what’s improving.

SEO takes patience. According to Google’s SEO Starter Guide, some changes show up within hours, while others take several months to have an effect. That’s why we set milestones and tracking metrics from day one: you always know where the project stands.

  1. 01Month 1

    SEO audit

    A crawl of the site, a review of Search Console and a comparison with your competitors.

  2. 02Months 1–2

    SEO strategy

    The year’s priorities: pages to create or revise, links to earn, order of the work.

  3. 03Months 2–12

    Execution

    Technical fixes, new content and link building, at the pace we agree on together.

  4. 04Every month

    Reporting & adjustments

    A monthly check-in on what moved and what we’re adjusting.

Sample twelve-month timeline; the real pace varies with the site’s size and the competition.

What you get, document by document

No hundred-page report that ends up in a drawer. Each document answers a simple question: what needs to be done, in what order, and what did it achieve?

  • The audit report

    The issues found, how serious they are and how to fix them, page by page when needed.

  • The action plan

    The tasks to carry out, ranked from highest return to least urgent, for your team or ours.

  • The dashboard

    Traffic from Google, queries, pages gaining ground and conversions, connected to your own Search Console and Analytics accounts.

  • The monthly review

    What was done, what moved and what we’re changing next month, in a few pages and a call.

Get cited when your customers ask an AI

A search can now end without a click: the answer appears right away, written by an AI that cites a few sources. For a brand, the question is no longer just “Am I first on Google?” but also “Does my name come up when someone asks ChatGPT for advice?”

We measure that presence across a set of questions your customers actually ask, and we build it on the same foundations as SEO: clear pages that answer precisely, consistent information everywhere your brand is mentioned, and citations on sites that AI considers trustworthy. To go further, our guide explains what Generative Engine Optimization is.

What an SEO engagement costs

The price of an SEO engagement depends mainly on four things: the size of the site, the competition on your search terms, the number of languages or countries you target, and how much of the work your team can handle. Rather than a flat package that fits no one, we prepare a quote once we’ve looked at your site.

The first conversation is about understanding your situation: there’s no commitment, and you walk away with an initial take on your site’s priorities.

How to choose an SEO agency

The market has excellent providers and some that are far less so. A few benchmarks are enough to sort them out, and they apply to us too.

What to expect

  • A written process, with steps and timelines
  • Recommendations that are explained and ranked by priority
  • Search Console and Analytics accounts in your name
  • A report that covers traffic and conversions, not just rankings
  • Clear answers about how links are earned
  • Experience in the countries and languages you target

Red flags

  • A guaranteed #1 ranking
  • Hundreds of links delivered in a few days
  • Mass-produced content with no editing
  • Accounts and data that stay with the agency
  • An unreadable report, or one sent without explanation
  • Refusing to detail what’s being done on your site

What we commit to

Your data stays yours. Your Search Console, Analytics and Google Business Profile accounts are created in your name; you add us as a delegated user without ever sharing your login credentials, and you can revoke that access at any time: everything stays in place if we stop working together.

Methods Google accepts. No private blog networks or paid links to manipulate rankings: we follow Google’s spam policies, because a penalty always costs more than the time saved.

No ranking promises. We commit to what we control: the work delivered, its timeline and honest measurement of its impact.

An agency built for international work. We work in French, English and Spanish, for sites targeting France, the United States, the United Kingdom or Spain, each with the words and search habits of its own market.

Your questions: SEO Agency

Can’t find your question? Ask us

What does an SEO agency actually do?

It analyzes your site and your market, fixes the technical issues that get in Google’s way, creates or improves content that matches what your customers search for, earns links from other sites, and tracks traffic and conversions every month.

When will I start seeing results?

Technical fixes sometimes show up within a few weeks; new content and links take longer. Google itself says some changes take several months to have an effect. We set interim milestones so you can track progress from the first months.

How much does an SEO agency cost?

We price each engagement after reviewing the site. The amount reflects the number of pages, the competition on your search terms, the languages you target and what your team can handle in-house.

SEO agency or SEO consultant: which should you choose?

An independent SEO consultant works well for a specific need or a small site. An agency brings several skills at once, technical SEO, writing and link building, and keeps the work going over time. The right choice depends mostly on the scope of the project.

Do you have to choose between SEO and Google Ads?

No, they complement each other. Ads bring visits from day one but stop when the budget stops. SEO takes longer to get going, then keeps bringing traffic without paying for every click.

Does AI search optimization replace SEO?

No. Answer engines like ChatGPT, Perplexity and Google’s AI Overviews rely on web pages they consider trustworthy. A site with strong SEO starts with a head start; AI-specific work adds to SEO rather than replacing it.

Can you do your own SEO?

Yes, partly. The basics can be learned, and free tools like Search Console help a lot. An agency becomes useful when the site grows, competition gets tougher or there isn’t enough time to keep a close eye on it.

Do you work with sites outside the US?

Yes. We work with sites targeting France, the United States, the United Kingdom and Spain, adapting keywords, content and links to each market rather than simply translating pages.
